sound conduit into communication either with said sound tube or with the tone arm of the machine. Other devices comprise a member adapted to be interchanged-with some part of the talking machine as in the case of an interchangeable sound box and radio receiver.

An object of this invention is to provide a simple and economical means of employing the sound conduit of a talking machine as a radio amplifier. A further object is to provide a means which'will enable the user, conveniently and quickly, to associate the sound conduit of a talking machine either with a record, by means of the sound box of the talking machine, or with a means of radio reception, and to readily efiect the change whenever desired without removal or substitution of parts, etc. ,7

The invention is susceptible of embodiment in various forms, some of' which are illustrated in the accompanying drawings, but it is to be expressly understood that these drawings are for the purpose of illustration only and are not'to' be construed as a definition of the limits of-the invention, reference being had to the appended claims for this purpose.

Fig. 7 is a detail in section of a further embodiment of the invent-ion; and

Fig. 8 is a plan view of the embodiment of F 1g. 7, various parts being removed for the sake of clearness.

Referring to the drawings, wherein like reference numerals indicate like parts, 1 is the record support of any suitable talking machine mounted in any suitable manner on a rotating spindle 2. 3 indicates any suitable tone arm, shown as provided with a gooseneck 4 and with a sound box 5. A tubular sound conduit 6, having an upwardly directed portion at the outer end thereof, is connected with any desired means of radio reception, such as the receiver 7, and is suitably mounted at one side of the record support 1; for the purpose of illustration, it is here shown pivotally supported in a bracket 8 by means of pins 9 (Fig. 4), said bracket being in turn pivoted at 10 to a suitable supporting member 11 which is secured by screws 12 to the support 13. Near its outer end the sound tube 6 is shown as provided with a member 14, suitably secured thereto as by means of screws 15, and having a forked end 16 adapted to engage with the spindle 2.

The tone arm 3 is provided at a suitable position inits length With an openin 17 in whichissuitablysecured,asbymeanso soldering, a connecting member 18. The lower end of said connecting member is formed in any suitable way for engagement and communication with the sound tube 6, being shown as of enlarged diameter in order to receive the outer end of sound tube 6 (Fig. 3).

The sound tube 6 is so positioned that when it is swung across the turn table so that the member 14 engages with the spindle, thereby holding the sound tube in position, the opening 17 in the tone arm will register with the upwardly directed open end of the sound tube 6, and the connecting member 18 will receive the end of said sound tube, thereby connecting the radio receiver 7 with the sound conduits or amplifier of the talking machine.

Another embodiment of the invention is illustrated in Figs. 5 and 6, wherein the sound tube 6 is supported in a stationary vertical position at one side of the turn table in any suitable manner, as by means of the bracket 19 and screws 20. In this embodiment the connecting member 18 is substantially cupshaped and is of much smaller diameter at the upper end thereof where it issecured in the opening 17 of the tone arm. The sound tube is so positioned that when the tone arm is swung clear of the turn table, the opening in the tone arm will register with the upper end of the sound tube. The smaller size of the opening in the tone arm in this embodiment tends to prevent any excessive leakage of sound from the tone arm when a record is being played.

A further embodiment of the invention is illustrated in Figs. 7 and 8 and provides a means of closing the opening in the tone arm when the radio receiver is not in use. This embodiment includes a ring 21 suitably secured in the opening 17 in the tone arm, as by soldering, and having a flapper valve 22 adapted to closesaid opening, as shown in dotted lines in Fig. 7, said valve being suitably pivoted thereto as by means of pin 23. The valve 22 is normally held in closed position by the action of a spring 24 and has a suitable projection 25 extending downwardly therefrom. A ring 26 is suitably supported in the end of the sound tube 6, being shown as resting on a shoulder 27, and has an upwardly extending portion 28 which is adapted to come into contact with the projection 25 on the flapper valve (Fig. 7 when the tone arm is operatively associated with the sound tube, this engagement causing the opening of the 1 flapper valve and connecting the sound tube with the sound conduits or amplifier of the talking machine. The opening 17 and valve 22 may be of any suitable size, and if desired said valve may be adapted to close the passage from said conduits or amplifier to the sound box when the radio receiver is in use, as shown in Fig.7.

. Means may also be provided if desired for completing the circuit through the radio receiver simultaneously with effecting the association of the sound tube and tone arm. As herein shown, these means include a downw'ardly extending projection 29 suitably secured to the tone arm as by means of screws 30 and having at its lower end an electrically conductive contact knob 31 which is insulated from said member 29 by means of the rings 32 ofany suitable material. When the tone arm is swung until the opening thereof registers with the sound tube, said contact knob 31 is in the embodiments of Figs. 1 to 6, such is not essential as it may be omitted, or 'if provided, may be formed integrally with or supported on the sound tube instead of the tone arm. Moreover, the opening 17 which is here in shown in the lower portion of the gooseneck, may be positioned at any other suitable point in the length of the tone arm, and may e a lateral or upward opening in the tone arm adapted to register with a suitably shaped and mounted sound tube. The circuit closing mechanism shown in Figs. 7 and 8 may also be employed with the other embodiments of this invention.

It will be apparent from the above description that this invention enables the user to readily connect the sound conduits or ampli fier of the talking machine with the radio receiver by merely swinging the tone arm into registry with the end of the sound tube and engaging the same therewith. The adjustment is simple and the apparatus may thus be converted practically instantly and with minimum effort from a talking machine to a radio loud speaking device or vice versa at will.

The embodiment illustrated in Fig. 7 has the additional advantage of closing the open ing in the tone arm when the instrument is used as a talking machine, thereby preventing leakage of sound. Likewise, when the switch mechanism herein described is combined with the apparatus, a single adjustment suffices to associate the sound conduits or amplifier with the radio receiver and simultaneously complete the circuit through said receiver.

Although several embodiments of the invention are illustrated in the accompanying drawings, it is to be expressly understood that the invention is not restricted thereto as other embodiments will now readily suggest themselves to those skilled in the art, while changes may be made in details of construction, proportion and arrangement of parts, and certain features used without other features, without departing from the spirit of this invention.
